I can blame the kid for making a commitment and then deciding to look around. I have no problem with looking around, but don't commit one place and then maintain your commitment while looking around. I agree, it is a big decision, and he should have made all of his visits BEFORE he committed someplace. So maybe his name isn't on a piece of paper, so I'll give you a better analogy; It's like giving your girlfriend an engagement ring, and then telling her you're banging all of her friends just to make sure you're not going to miss anything when you're married.
I made a pretty big commitment when I was 17 years old that decided the course of my life, and once I gave my word, there was no backing out, so spare me the drama about what he's going through, because thousands of kids like me do it every year.
